Austin and Ty Dillon don't claim to have a sibling rivalry, but there is some element of competition in their bloodlines. There's also little coincidence that their career arcs have strikingly similar parallels.

Austin, 21, will jump to the NASCAR Nationwide Series this season, one year removed from becoming the youngest champion in the history of the NASCAR Camping World Truck Series. Ty, who will turn 20 the day after the Feb. 26 Daytona 500 (FOX, 1 p.m. ET), will be taking his older brother's place in the truck series, fresh from an impressive march to the ARCA series title in 2011.

Both are champions, both are moving up, both will campaign the famed No. 3. But does one brother have an advantage over another? It depends on who you ask.

"So far, I've got more wins, so me, and I'm always going to say me," Ty Dillon says with a wink. "That's the answer to that question, but I believe in my brother, too. It's the both of us right now; it's more about the Dillon name succeeding in NASCAR."

True enough, Ty claimed a 7-2 margin over his brother in the win column after last season, a point Austin readily concedes.

"Ty is his own guy, you know. To me, he kind of creates his own identity with the way he likes to drive," Austin Dillon said. "We work together well; we push each other tremendously, so it's nice having a very talented brother to make you want to do your best each and every week."

As they make the leap up the ladder this season, both Dillons will lean on each other as resources on a Richard Childress Racing team laden with them. But two more generations of family will also have their eye on the farm -- father Mike Dillon is the RCR general manager and their grandfather is the legendary owner and team namesake.

Advancing deeper into the ranks of NASCAR's top three national series may seem like pretty heady stuff for two relatively young drivers, but based on their reactions to questions on last week's NASCAR Sprint Media Tour presented by Charlotte Motor Speedway, they seem unfazed by any perception of pressure.

"I try not to think about it too much," Ty Dillon said. "I focus on my main goal, which is winning races and fighting for a championship. I've been given the greatest opportunity in the world to drive for my family, which is an awesome organization in RCR."

For his part, Austin Dillon isn't treating his transition as a millstone around his neck, either.

"There's always pressure in whatever you do, but it's how you handle it and if you take advantage of it," he said. "I think, in my situation, I like pressure. I feel like pressure makes you rise to the occasion most of the time. The more you have, you have to go out and do something about it or handle it the right way."

Rocky Mountain High for Regan

Regan Smith's stunning breakthrough in winning the Southern 500 at Darlington Raceway was one of the brightest moments of the NASCAR Sprint Cup Series last season. But one of his more dramatic moves took place far west of sandy South Carolina.

Smith wanted to be closer to his Furniture Row Racing team. That meant moving from the Charlotte-area hub of stock-car racing to Denver, the western-most point among major NASCAR race shops.

"It's certainly different and took a little bit of time to get used to initially," Smith said. "The first time that (wife) Megan called me and said there's a bear on our back porch and she was scared half to death was a pretty unique day."

Since then, the Smiths have seen bobcats, elk and other wildlife from their remote home. What the scrappy single-car team has seen since the Smiths' move is an extreme commitment to their efforts.

"It was definitely a big deal," said Pete Rondeau, Furniture Row's crew chief. "To be able to see the driver, it's a big thing for the people in the shop, to see that he has the drive and the desire to do this and to be a big part of this team."

No F1 for Ganassi

Team owner Chip Ganassi managed one of the best lines of the media tour when asked about the possibility of expanding his already diverse motorsports empire into Formula One.

"There was a time in my life when I would've thought about that," Ganassi said. "When I start to think about that, I go lay down until that feeling goes away."
